The Gaia mission and its data releases are driving a revolution
in our understanding of the Milky Way and its constituents. In this
talk, I will highlight a few of the results stemming from the
analysis of the truly spectacular datasets produced so...
The study of linear spaces of matrices arises naturally (and
independently) in many different areas of mathematics and computer
science. In this survey talk, I will describe some of these
motivations, and state and prove some (old and new)...
The operator product expansion of massless celestial primary
operators of arbitrary spin is investigated. Poincare
symmetry is found to imply a set of recursion relations on the
operator product expansion coefficients of the leading singular
terms...
